“People always ask, ‘What is your greatest failure?’ I always have the same answer – We’re working on it right now, it’s gonna be awesome!” - Jim Coudal
"The key to success is to be cheerful in the face of constant failure." - my take on failure
"Hara Hachi Bu. (腹八分)" - a Okinwana saying which means you should eat until you are 80% full (not sure if my translation into Japanese is correct)
There is also some kind of Japanese saying that goes "made stupid by peace." I'm not sure if this is really a Japanese saying, so correct me if I'm wrong. The idea is that the peace and comfort we experience in first world countries makes us lazy and complacent.
